Fabrication of polymer parallel optical waveguide with GI-circular-core using dispenser

As an innovative fabrication method of polymer optical waveguides, the "Mosquito Method" is introduced, which utilizes a dispenser to extrude a viscous monomer on substrates directly. By optimizing the extruding conditions, parallel waveguides with circular GI-cores are successfully fabricated using the Mosquito Method. The optical characteristics of the polymer parallel optical waveguides fabricated by the Mosquito Method are also discussed.
